I earned my MSW from the University of Southern California in 2021, and my passion for mental health work has only deepened since then. I work with teens and adults (ages 12 and up) who are navigating anxiety, depression, PTSD, and the often-complicated layers beneath them. I draw from Cognitive Behavioral Therapy (CBT), Mindfulness, and Motivational Interviewing—not as a one-size-fits-all plan, but as tools we can use together to meet your needs and goals. In session, I show up with curiosity, care, and respect for your lived experience. You don’t have to go through this alone.
I work with teens and adults ages 12 and up, specializing in anxiety, depression, and PTSD. Using Cognitive Behavioral Therapy (CBT), Mindfulness-Based approaches, and Motivational Interviewing. You'll recognize stuck patterns and reconnect with your strengths. Our work is collaborative, practical, and centered around what matters most to you.
Starting therapy can feel overwhelming, but you don't have to navigate it alone. If you’re ready to ease the pressure, find steadier ground, and move toward a life that feels more connected and fulfilling, I would be honored to work with you. Reach out today to get started.
